Abstract
The utility model discloses a gas water heater, which comprises a shell body. A heat exchanger is disposed in the shell body, and a condensation heat exchanger is arranged at the upper portion of the heat exchanger. The condensation heat exchanger comprises heat exchange tubes, a water inlet and a water outlet. The water inlet, the water outlet and the heat exchange tubes are communicated. The gas water heater is characterized in that the number of the heat exchange tubes is three, the head and the tail of one heat exchange tube is communicated with the other two heat exchange tubes, one ends of the two heat exchange tubes are respectively communicated with the water inlet and the water outlet. The three tubes are distributed in a triangular shape, and the head and the tail of one of the three tubes are communicated with the other two tubes through a U-shaped tube. Due to the fact that the heat exchange tubes are composed of three tubes, when passing through the condensation heat exchanger, discharged gas can be fully contacted with the heat exchange tubes, heat in the gas is led to be fully absorbed by cold water passing through the condensation heat exchanger, and accordingly heat exchange efficiency of the gas water heater is improved.
Description
Technical field
The utility model relates to a kind of gas heater, the high gas heater of specifically a kind of heat exchanger effectiveness.
Background technology
For improving the efficiency of water heater; Increased a condensed heat exchanger in the existing gas heater; The effect of condensed heat exchanger is that the combustion gas of discharging further is cooled to below 100 degree; Steam in the combustion gas is condensed into liquid, and the cold water that the heat of water vapor condensation liberated heat and combustion gas cooling is flow through condensed heat exchanger absorbs, thereby reaches the purpose that improves efficiency.Heat-exchange tube in the existing condensed heat exchanger is made up of two pipes, and water inlet and delivery port are separately positioned on the two ends of heat-exchange tube.This condensed heat exchanger is owing to only be made up of two pipes, the heat in the combustion gas can not be fully and the water in the condensed heat exchanger carry out heat exchange, have the low shortcoming of heat exchanger effectiveness.
Summary of the invention
The purpose of the utility model provides the high gas heater of a kind of heat exchanger effectiveness.
The purpose of the utility model realizes through following technical scheme.
A kind of gas heater comprises housing, is provided with heat exchanger in the housing; The top of heat exchanger is provided with condensate and heat exchanger; Condensate and heat exchanger comprises heat-exchange tube, water inlet and delivery port, and water inlet, delivery port communicate with heat-exchange tube, it is characterized in that: said heat-exchange tube comprises three pipes; Wherein the head and the tail of a pipe are connected with other two pipes, and an end of these two pipes is connected with water inlet, delivery port respectively.
The distribution triangular in shape of said three pipes, wherein the head and the tail of a pipe are connected with other two pipes through the U-shaped pipe.
The utility model compared with prior art has the following advantages.
Heat-exchange tube in the utility model gas heater comprises three pipes, and wherein the head and the tail of a pipe are connected with other two pipes, and an end of these two pipes is connected with water inlet, delivery port respectively.Because heat-exchange tube is made up of three pipes; The combustion gas that is discharged from is fully contacted with heat-exchange tube through condensate and heat exchanger the time; The cold water that heat in the combustion gas is flow through condensed heat exchanger is fully absorbed, thereby improve the heat exchanger effectiveness of gas heater.
Description of drawings
Fig. 1 is the structural representation of the utility model gas heater;
Fig. 2 is the side view of the utility model gas heater.
The specific embodiment
Below in conjunction with accompanying drawing the utility model gas heater is described in further detail.
Like Fig. 1 and shown in Figure 2; The described gas heater of the utility model comprises housing, is provided with heat exchanger in the housing, and the top of heat exchanger is provided with condensate and heat exchanger; Condensate and heat exchanger comprises heat-exchange tube 1, water inlet 2 and delivery port 3, and water inlet, delivery port communicate with heat-exchange tube.Heat-exchange tube comprises three pipes, and wherein the head and the tail of a pipe are connected with other two pipes, and an end of these two pipes is connected with water inlet, delivery port respectively.The distribution triangular in shape of three pipes, wherein the head and the tail of a pipe are connected with other two pipes through the U-shaped pipe.Because heat-exchange tube is made up of three pipes; The combustion gas that is discharged from is fully contacted with heat-exchange tube through condensate and heat exchanger the time; The cold water that heat in the combustion gas is flow through condensed heat exchanger is fully absorbed, thereby improve the heat exchanger effectiveness of gas heater.
